SPECIFICATION formingpart of Letters Patent No. 714,251, dated. November 25, 1902. Application filed June 23, 1902. Serial No. 112,755. (No model.)

To ctZZ whom, it may concern.-

Be it known that I, FRANCIS A. SPENCER,

a citizen of the United States, residing at Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sectional Columns for Architectural Purposes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawto enable the glue to be more perfectly and evenly distributed throughout the joint, and

to secure other advantages and results, some of which may be referred to hereinafterin 1 connection with the description of the worki ing parts.

a hollow column.

The invention consists in the improved sectional column and in the arrangements and f combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings,

in which like letters of reference indicate corresponding parts in each of the several figures, Figure l is a transverse section of the column,,showing the same in angular form. Fig. 2 is a similar section, showing said column afterthe same has been placed in a lathe and turned. Fig. 3 is a detail end View of one of thesections of the column, showing the same on a larger scale. Fig-4 isan elevation showing portions of a complete column, and Fig. 5 is an edge View of one of the strips or sections of the said column. In said drawings, a indicates the column,

which is composed of a series of longitudinal segmental strips or sections 2), of wood, arranged edge to edge in annular series to form The edges of said strips 19 b are each molded or cut in a molding-mill 1 or otherwise in the manner shown in detail in Fig. 3, where the opposite edges 0 d are formed at their outer parts, as at c d, on radial lines from the center of the column, the said radial lines extending out, preferably, to the periphery of the column, as'shown in Figs. 1 and 2. Toward the inner faces of the strips, at one side thereof, the said strips are each provided with tongues e, extending from the main radial lines (1' laterally outward, as shown. The said tongues e at opposite sides are provided with surfaces e 8 which lie at inclinations greater than right angles with respect to the radial lines or surfaces (1, the said tongues e thus being V-shaped' in crosssection and tapering to narrow edges f, which, however, are preferably not sharp edges, but are preferably slightly truncated, as shown. The inner surfaces e of the tongues e are preferably at right angles to the central axial plane it of the strip and cross the radial edge planes (1, extending therefrom inwardly toward the-center of the strip and forming a wall to a groove 1'. The said groove 2' at its ex treme inner end may be provided with a narrow flat bottom 41, as shown. The wallj of the groove 11 opposite the wall 6 extends from said bottom 1." to a point at or approximately attheline or plane d, forminga tapering tongue 7r; with the back surface Z of the strip.

At the opposite side or edge a of each strip 1) the same is recessed at a point toward the rear surface Z, as at m, the wall m of the said recess being formed substantially at right angles to the axial line h.

The wall m of the recess m. forms a tapering tongue at with a wall or surface n, which extends from the small edge of the tongue 72 forward and toward the axial plane 71. at an inclination to the said plane and crosses the radial plane 0, formingabroad surface adapt;

ed to coincide with and lie against the surfaces o of the next contiguous strip. Said surface or wall n forms a V-shaped tapering groove 0 with the forward wall 0, lying substantially parallel with the rear surfaces Zm. Said tapering groove 0 coincides in shape with the tongue e of the next contiguous strip and is adapted to receive the same, the walls o n nicely meeting the walls e e of said tongue. The radial surface 0, extending to the peripheral surface 10, is engaged by the surface d of the next contiguous strip.

It will thus be observed that the grooves and recesses are correspondingly tapering and the walls of the said tongues and grooves do not come into close contact when the strips are placed together until the surfaces 0 and d are finally brought together, and thus closed chambers are not formed into which the liquid or semiliquid glue can be entrapped when the parts are pressed together to 0bstruct the closing of one section hard and close against the other. By my construction I am enabled to secure a very close contact of the several strips, and the applied glue is distributed over the meeting surfaces, as will be evident, all of which conduces to a more permanent and durable union of parts. Furthermore, each strip at its opposite sides provides a tongue and groove, projecting, respectively, out from and in from the radial lines o d of the sections and providing long meeting surfaces 6 it, over which the glue is evenly and thoroughly distributed, the said surfaces lying in from the outer peripheryp of the column, so that dampness and other atmospheric influences are most thoroughly prevented from acting upon the glue withinthejoint,which,furthermore,conduces to a permanent and durable union of the parts and secures mechanically a strong and rigid union.

Having thus described the invention, what I claim as new is- 1. The improved sectional column, comprising an annular series of strips or sections, one strip or section of which has a tapering tongue extending out from the radial edge surface, the inner wall of which tongue is a continuation of and forms the outer wall of a tapering groove 2', lying in from the planeof tudinally tongue-and-grooved at opposite edges to coincide with the sections next contiguous, one strip or section being at one edge formed on a radial line or plane 61, near the peripheral surface 19, of the strip, toward the inner part of said strip, formed on lines or planes inclined to said radial line or plane d, said inclined lines or planes forming a V- shaped tongue and at the inner side of said tongue the said one edge of the strip having a V-shaped groove extending inwardly or toward the center of the strip from said radial plane, and the other edge of said strip having a recess m, at the back of the strip, and extending out from the radial plane of the surface a, a V-shaped tongue next in order forward from said recess, a V-shaped groove extending in from the radial plane of said edge and at the outer side of said groove having a radial surface extending from said groove to the periphery of the strip, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 6th day of June, 1902.

FRANCIS A. SPENCER.
